Hi!
About USB devices hardware. There are some circumstances, when USB device fails (but about burning out i'm hearing first). We are developing some sort of data reading equipment, with USB interface too, and some problems arise with HP notebooks (Omnibook). In general, some cheap USB interface chips doesn't follow full USB specification, particulary in powering scheme, exactly this was our problem with HP. On these notebooks doesn't work some flash drives too.
Maybe you can send me partlist or schematics from these burned out dongles, as i don't have one? This will help ...
Check voltage level on your computer USB lines.
Regards,
Raimonds
